Food-drug interphase products, referring to nutraceuticals in this study, are a category of health products containing a combination of food ingredients with active substances for oral consumption. Many of these products are marketed as an alternative to prescription medicine to treat various ailments despite the lack of scientific evidence, influencing patients with chronic diseases to consume nutraceutical products. This study aimed to determine the prevalence and factors associated with knowledge, attitude, and practice of nutraceutical use among patients with chronic disease attending to the outpatient clinic. This is a cross-sectional study involving patients with chronic disease at the outpatient specialist clinic. Samples were recruited from the outpatient clinic using convenience sampling. Data was collected using a self-administered questionnaire, which was self-constructed and validated. We found that the use of nutraceuticals was prevalent among 17.9% of respondents. More than half (60.9%) of the respondents have poor knowledge of nutraceutical and 53.1% of respondents have a positive attitude towards nutraceutical. Gender and morbidities were the factors associated with the practice of nutraceutical usage. Female patients are more likely to have increased use of nutraceutical than male patients and patients with multiple morbidities have higher odds of using nutraceutical than patients with single morbidities. There is a high number of patients who consume nutraceutical products and public knowledge of nutraceutical needs to be improved further. The government should develop appropriate regulation and monitoring of nutraceutical products.
食品-药物中间相产品，在本研究中是指营养保健品，是一类含有食品成分与活性物质组合的口服保健品。尽管缺乏科学依据，但许多此类产品作为处方药的替代品进行销售，用于治疗各种疾病，这影响了慢性病患者消费营养保健品。本研究旨在确定在门诊就诊的慢性病患者中营养保健品使用知识、态度和行为的患病率及相关因素。这是一项涉及门诊专科诊所慢性病患者的横断面研究。样本采用方便抽样法从门诊诊所招募。数据通过自行编制并经过验证的自填式问卷收集。我们发现，17.9%的受访者普遍使用营养保健品。超过一半（60.9%）的受访者对营养保健品了解甚少，53.1%的受访者对营养保健品持积极态度。性别和发病率是与营养保健品使用行为相关的因素。女性患者比男性患者更有可能增加营养保健品的使用，患有多种疾病的患者比患有单一疾病的患者使用营养保健品的几率更高。有大量患者消费营养保健品，公众对营养保健品的了解需要进一步提高。政府应制定对营养保健品的适当监管措施。
